WINDOW-SCREEN.

Specification of Letters Patent.

Patented July 17, 1917.

Application filed May 1, 1916. Serial No. 94,824.

T0 all whom it may concern.'

Be it known that I, ANTONIO V. BRUN, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California,have invented certain new and useful Improvements in Window- Sereens, ofwhich the following is a specilication.

This invention relates to improvements in window screens and has as itsobject the construction of a screen which will cover the entire window,but when not in use is rolled out of sight and does not obstruct thevision through the window.

Another object of my invention is to provide a screen which may beattached to windows of ordinary construction with the minimum expenseand trouble; and

Lastly my invention aims to provide an improved screen which costs nomore than the ordinary Xed or stationary screen as it is used on theoutside of the window.

With these and other objects in view the invention consists in the novelconstruction, combination and arrangement of parts herein described, andmore specifically pointed out in appended claims.

Reference being had to accompanying drawing forming a part of thisspecification,

Figure 1y is a view in vertical section through the window and screen.

Fig. 2 is a view in section through a window having a modified form ofthe screen.

Fig. 3 is a view in front elevation of a window showing my improvedscreen attached thereto.

Fig. 4 is an enlarged view in section through the window frame showingthe track in which the screen moves.

Fig. 5 is a similar view of the track for the modiied form.

Fig. 6 is a view in section through the lower end of the screen.

Fig. 7 is an enlarged fragmentary. view of the lower corner of thescreen.

Referring to corresponding parts in the several views by the samenumerals of reference, 1 denotes my improved screen which has a widthequal to the window and a length sufficient to entirely close the same.This screen is attached to a roller 2 of the type used in the rollerwindow shades, this roller being mounted as hereinafter described. Tothe lower end of the screen is attached a double cloth of Aleather piece10 which is stitched as at 12 forming two 1ongitudinal pockets 13 and 16in which are held the strip 4 and a bar 11 respectively. The latter baris provided with vprojecting ends which engage the trackways that act asguides for the edges of the screen. The side edges of the screen areprovided with a binding 14 to eliminate wear and cause it to wind betterupon the roller 2. In the binding 10 is provided one or more holes 15suitably reinforced as by a buttonhole stitch.

A trackway 5 is attached to the window stop on each side, and extendsupwardly to a point adjacent the top of window. The screen surroundingthe roller 2 is provided with the cylindrical casing 6, having anopening 7 on the bottom, which at the side forms a substantialcontinuation of the trackway 5. The window stool is provided with hooks8, the bent end of which is adapted to engage through the openings 15above the wooden strip 4t, thereby holding the screen in its lowerposition.

The modied form of trackway shown in Fig. 5, is used when the screenroller is attached to the head casing of the window as shown in Fig. 2.This trackway is a Z-bar shape so that when one leg is attached to thewindow casing a groove 9 is formed in which the screen and rod 11 areadapted to slide.

In the form shown in Fig. 2 the brackets 18 for the window shade 17 arespaced a suiiicient distance apart to enable the screen to slidetherebetween and the roller may be mounted upon brackets 19 and thecasing 6 omitted. In the form shown in Fig. 1 the roller is mounteddirectly in the end plates of the casing, the one end of the casinghaving a cap 6 to permit the insertion of the screen.

The operation is as follows: When the window is open at the top, thescreen is pulled down to the top of the upper sash, wherebythe openingis entirely screened and yet an unobstructed view is had throughl theglass. In case it is desired to have the lower sash raised then thescreen is pulled down until the rod 16 rests on the window stool,thereby effectively screening the entire window. With easement windowsthe screen .is entirely unwound from the roller and fastened to the sillby means of hooks 8. When it is desired to close the windows orotherwise change the opening, this may easily be accomplished byunhooking the lower part4 of the screeny allowing the same to be Woundupon the roller in the manner of the ordinary shade.

In the modified form shown in Fig.k 2, the roller is mounted above theshade roller 17, W

` instalhbut otherwise is as efficient in operation; K

While I have shown the preferred embodi ment of my invention, it Will beunderstood that minor changes may be made in detail design' Withoutdeparting` from the spirit of the invention. Y
